SPECIFICATION forming part of Letters Patent N o. 637,207, dated November 14, 1899;

Application filed November I2, 1897. Serial No, 658,256. (No model.)

To zr/ZZ zul/1,0m it 'may concern.-

. Beit known that we,W1L`LIAM I-IINDLEY, of Hoboken, in the county of Hudson and State, of New Jersey, and JOSEPH W. I-IARDING, of

New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Bundling-Machines, of which the following is a full, clear, and exact description.

ro Our invention relates to improvements in machines for bundling kindling wood or analogous material, and particularly to machines which are intended to compress and form a bundle of long sticks, which can then be separated into a series of shorter bundles.

The object of our invention is to produce a comparatively simple and extremely powerful machine which is adapted to automatically receive the sticks and compress them zo into firm bundles of uniform size, which has means for binding and for applying labels to the bundles, which is adapted to discharge the bundles upon a carrier, so that they can be conveniently removed ready for further 2 5 separation, and which in general is adapted to operate very rapidly and without danger of getting out of repair.

To these ends our invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate 3 5 correspondin g parts in all the views.

Figure 1 is a side elevation of our improved machine. Fig. 2 is a broken rear end view of the same. Fig. 3 is a broken vertical cross-section on the line 3 3 of Fig. l. Fig. 4

4o is a detail sectional plan view on the line 4 4 of Fig. 3, showing the means for actuating the end plates which temporarily support the bundleswhilethelatterarebeingcompressed. Fig. 5 is a detail longitudinal section of the gear and ratchet mechanism employed in part for feeding the labels. Fig. 6 is a broken end view of the mechanism shown in Fig. 5. Fig. 7 is a fragmentary perspective view of a portion of one of the strips of labels. Fig. 8

is a longitudinal section, partly in elevation, 5o of one of the knotters and operating mechanism therefor, illustrating a portion of the forming-arms with a portion of the label feeding and holding mechanism thereon, together with a portion of the compressing-jaws in po- 5 5 sition to have the bundle bound by theseveral strings or twines. Fig. 9 is a detail plan View, partly in section, of the knot-tying mechanism for one of the strings; and Figs. 10 to 13, inclusive, are detail views illustrating different developments of the knot While and after being tied.

The machine has a suitable frame 10, which can be made in any convenient form, the main thing being to have it very substantial, and at the top of this frame is a slideway formed by the side plates 11 and bottom plate 12, this slideway guiding a tray 13,which reci procates backward and forward therein, being actuated by connecting-rods 14 at its ends, which 7o latter can be moved in any convenient way, and the tray 13 holds sufficient material to form a bundle, although the bundle thus formed is very long, as will hereinafter appear, and is adapted to be subdivided into numerous short or commercial bundles.

The wood prior to being bundled is delivered into the tray 13 from a carrier 15 of ordinary construction, and when the tray is pushed rearward in the slideway 1l 12 the surplus or overflow is pushed back by the revolving spur-wheel 16, which is journaled in suitable supports 17 and the tray will thus slide easily rearward and will discharge just sufficient material to form a bundle, the dis- 8 5 charge being through the opening 18 in the bottom plate 12. (See Fig. 1.) After the wood is discharged through the opening 18 the tray 13 returns to place. We have shown no mechanism for actuating the rods 14, but it is obvious that any usual device for this purpose can be employed.

IVhen the wood is dropped from the openbottomed tray 13 through the opening 18 it falls between a series of oppositely-arranged 95 forming-arms 19 19a, which give to the wood the approximately cross-sectional shape of a bundle, these arms being curved oppositely by the arms 19.

4vided with a gear-wheel 315 and willi a ratchetand arranged to support the wood between them, as shown clearly in Fig. 1, and they are secured to shafts 20, which are journaled on the frame on opposite sides ofthe opening 18.

Thile the wood is settlinginto the arms 19 19a it is shaken down, so that the sticks lie closely by means of the vibratory motion which is imparted to the arms 19, although such a motion can be imparted to both the arms 19 and 19, if desired. Any suitable means can be employed for vibrating the arms and the machine can be worked without this vibratory motion, but we find it desirable. As illustrated, t-he Vibratory movement of the arms is imparted from a wheel 21, (see Fig. 1,) which is jourualed on the frame 10 and which connects, by means of the strap 22, with a crank 23 on one of the shaft-s 20. The wheel 21 is impelled in one direction by a spring 24 and in the opposite direction by means of a projection 25 on the wheel and a bell-crank 2G, one end of which engages the said projection, the bell-crank being pivoted, as shown at 27, and having its opposite end in engagement with a toothed wheel 28, which is journaled on the frame 1() and, as illustrated, is actuated by pulleys 29. In Fig. 1 these pulleys are purposely removed.

Thile the wood is held between the arms 19 19 a series of paper labels from the roll 30 is fed beneath the wood, and after the bundles are formed and the labels held in place, as hereinafterdescribed, the wood is severed across between the several labels, thus forminga whole series of commercial bundles, each 0f which is provided with a label. rl`l1e individual labels on the roll are separated by a line of perforations, as at 30, Fig. 7, so thatthey will tear apart at this point when the wood is dropped, as described presently. As illustrated, these rolls 30 are supported on a spindle 31, which is held in the slots 32in the arms 19, and the labels are fed forward by oppositely-arranged friction-rolls 33, which are secured to the shafts 34 and 35, carried The upper shaft 35 is prowheel37, (shown best in Figs. 5 and 6,) and the ratcl1et-wheel is prevented from turningin the wrong direction by a detent 33. The ratchetwheel is tight on the sha-ft 35 and the gearwheel 36 is loose, and the two are connected by springpins 39, which are held in the ratchet-wheel and the ends of which enter shallow sockets 4U in the gear-wheel 36, as shown clearly in the figures referred to. 'lhe gear-wheel engages the toothed segment 41 ou the lower end of a rigid arm 4:3, which is held on the two shafts 20. It will be seen then that when the arms 19 19 are opened to drop the wood the gear-wheel 3G will move across the toothed segment 41, with which it meshes, and will turn loosely, while the detent 3S will prevent the ratchet-wheel 37 from turning, the pins 39 slipping out of the sockets 40. Vhen, however, the arms 19n swing forward to close with the arms 19 and be in position for receiving the next tray full of wood, the reverse action takes place, the ratchet-wheel and gear-wheel are turned in the opposite direction, the detent 38 slipping over the teeth of the ratchet-wheel, and the friction-rolls 33 are turned so as to feed forward the labels 30. When the labels are thus fed forward, they are caught at their free ends by clamps 43 and held against the lower extremities of the arms 19, as shown in Figs. 1 and 8. These clamps 43 are each pivoted, as shown at 44, and are held by a spring 45, so as to close tightly against the labels, the spring being secured to the frame l() and to an arm 4b' on the Shaft 44. The forward edges of the clamps are rounded and have projections 47 on the under side, which are adapted to slide over the catches 48, and thus permit the clamps to tip sufliciently to firmly grip the labels.

- On the opening'of the arms 19 19, as specitied, the clamps swing forward and their outer ends engage strips 49, which tilt them and permit the labels to slip out, this action taking place just after the labels break from the rolls 30, so that. the labels will drop down, with the wood, between the compressing-jaws 51. These arms 19 19 close by gravity and are opened by the opening of the jaws 51, the arms 19 19 having projections 50 at their lower ends, which engage the upper ends of the jaws, the latter being operated by compressing the wood into the desired shape of bundles, as will be hereinafter described.

The twine, string, or wire with which the bundle is bound is stretched across beneath the labels, so as to descend with the wood, and after the wood is compressed between the jaws 51 the strings or cords are tied or secured and the labels thus held in place, the number of rolls of labels and binding strings or twines corresponding to the number of shorter or commercial bundles or packages into which the larger bundle is to be ultimately divided. The strings or other binding material may be tied or secured in any desired manner; but we prefer to provide an automatic knotter and mechanism therefor, and for this purpose we have illustrated a device, as at 52, for each string or twine, which may be arranged upon the supports 52 and 53 and operated from the shafts 54 and 55, which are supported on brackets 5G and 57, as will be hereinafter more particularly described. ever, is not claimed per se in this application, but only in combination with other features ofthe machine, as such devices may be of any desired form and construction, and asl the particular form of knotter shown will be included in and form a parl of a separate application, though it is to be understood that in some instances, if desired, the binding may be done by hand or the bundles secured in any convenient manner.

The jaws 51 form between them an opening 58, which is of the shape of the compressed IIO The linotting mechanism, howbundles, and the jaws are connected by pins 59 with slide-blocks 60 60a. The jaws loosely engage the pins 59, which serve merely as guides, and the pressure is applied to the jaws from the slide-blocks through the coil-sprin gs 62, which encircle the pins and act as cushions, so that in case of any excessive quantity or unevenness of material between the jaws the cushions will yield and prevent the connecting mechanism from being strained. The springs are stift' enough, however, to enable the jaws to be pushed together with sufficient force to suitably compress the wood.

The slide-blocks 60 60u move in slideways 61, and the slide-block 60 is moved directly by the toggle-levers 63, which are pivoted to the slide-block, as at 64, and to the frame 10, as at 65. The togglelevers connect at their meeting ends with a pitman or connecting rod 66, which has the usual take-up 67 for adjusting its length, the rod 66 connecting at its lower end With a vertically-moving slideblock 68, which reciprocates in a slideway 69 and is actuated by a cam 70, the cam being cut away on one side, as shown at 71, to permit the rise of the block 68 after it has been depressed. From the pivot 64 extends a link or arm 72, which connects with the upper end of the walking-beam 73, which is pivoted on the stud 74, the latter being held on suit-able brackets 75. The lower end of the walkingbeam connects, by means of an arm or link 76, with the second slide-block 60a, so that when the slide-block 68 is moved down by the cam 70 the toggle levers are straightened, the walking-beam 73 tilted, and the slide-blocksA 60 and 60n moved simultaneously toward each other, and thus act on the springs 62 and jaws 51 so as to slide the latter together.

The several jaws 51 are secured to rods 77, which slide through supports 78, formed on the frame 10, and the outer ends of the rods are encircled by springs 79, which engage the support 78 and abutments 80 on the ends of the rods, and the pressure of the springs is sufficient to pull back the jaws 51 and the connecting mechanism and raise the slideblock 68 when the latter comes opposite the cut-away portion 71 of the cam 70.

` When the long sticks drop from the arms 19 19a between the jaws 51, they are caught on plates 81, near opposite sides of the machine, and held in position to be compressed by the jaws. The plates 81 are each secured to the top of a tilting-arm 82, which is held in a substantially Vertical position opposite the meeting point ofthe jaws, as best shown in Fig. 3, and is pivoted at 83, so as to swing in a plane at right angles to the jaws, the lower end of the arm being bent inward and provided with a weight 84, the heft of which is sufficient to swing the plate 81 inward into the path of the descending wood. The object of the plates 81 is to support the Wood until the jaws 5l are near enough together to firmly grip it, and when the jaws meet and the wood is compressed the plates 81 must swing outward, so as to permit the wood to drop after compression. To this end each arm 82 is provided on its inner side with an inclined projection or cam 85, (see Fig. 4,) which extends in the path of thejaws 51, and when the latter nearly meet they engage the said inclined cam and, acting thereon, tilt the arm 82 outward, thus permitting the Wood to drop from the plates 81, and the latter cannot again swing in until the compressed bundle is dropped.

When the jaws 51 open, the bundle drops upon a carrier 86 of the ordinary kind and is conveyed away and cut up in suitable lengths. This carrier has dogs 87 thereon to engage the wood and prevent it from displacement and moves over an ordinary roller 86u. Its shaft 88 is provided with a gearwheel 89, meshing with a gear-wheel 90, and the latter is journaled 0n the frame 10 and driven by a ratchet-wheel 91, with which it is connected,this ratchet-wheel being stepped around by a pawl 92, which is pivoted on the link 93, and the latter is journaled on the shaft 94 of the gear-wheel 90 and connects by a link 95 with one end of a rock-plate 96, which at its lower end is pivoted to the frame 10, as shown at 97, and at its other end is slotted, as shown at 98, so as to conneet with one end of the pitnian 99, and the latter is also pivoted to a swinging arm 100, pivoted on the frame 10, as shown at 101. The arm is moved bythe cam 70, which it follows, being pressed against the same by a suitable spring 100i.

It will be seen then that when a bundle is dropped the cam 70 acting on the arm 100 and pit-man 99 will tilt the rock-shaft 96 and actuate the links 95 and 93 so as to cause the pawl 92 to act on the ratchet-wheel 91, and thus move the carrier 86 through the medium of the gears 89 and 90.

The shaft of the cam 70 is provided with a gear-wheel 102, engaging the gear-wheel 103 on the driving-shaft 104, which is actuated by the pulley 105; but it is of course obvious that any ordinary driving means can be applied to any of the moving parts without affecting the principle of the invention.

The knotting mechanism, as illustrated, has a slide 106 arranged in the support 52 and carries atone end thereof a clamping-jaw, as at 106, and has a bar or rod 107 pivoted thereto, as at 107, which is provided with a clamping-jaw 1073, between which and the jaw 106la the twine or string is adapted to be clamped and fed forward from a reel (not shown) or other source of supply, said jaws being normally pressed apart by means of a spring, as at 108. On the slide 106 may be arranged a bracket 109, which is connected, by means of a rod or link 110, to the lower end of an arm or lever 111, which is arranged to swing or oscillate on the transverse shaft 111i. This lever may be provided with a cam projection 112, which is adapted to be engaged at the proper time by the cams 113 IOO IOS

4 eamo? and 114, arranged upon the disk 115, which latter is secured to the transverse shaft 116, the said cams being adapted to engage the cam projection 112 and advance or force the clamping and carrying jaws 106 and 1071 inwardly for the purpose to be presently explained. The sliding and clamping jaws are retired or brought back to different positions by means ofthe cam projections 116 and-117 on the disk 118, which projections engage a sliding block 119, as at 120, the said sliding block being slotted at both ends, so as to span the transverse shafts 116 and 111, and being provided with an aperture which engages a pin 121 projecting outwardly from the leveror arm 111, so that as the disk 118 rotates the cam projections thereon, engaging the sliding block at the point 120, will throw the lower end of the arm 111 rearward or outwardly, and through the pitman or connecting-rod 110 retire the slide 106 and the clamping-jaws carried thereby.

In order to cause the clamping and carrying jaws 106 and 1071 to positively engage the string or twine or be released therefrom, we may pivot a rocking block or arm 122 to the bracket 109. On each end of this rocking arm may be arranged wedge-shaped cams or blocks 123 and-124, which are adapted to engage the inner edge of the bar 107, carrying the jaw 10711, so as to throw the s-ame inwardly on its pivot, while the reverse or open position is obtained through the pressure of the y spring 108. Adjacent to the Wedge or cam shaped blocks 123 and 124 are the rods or studs 125 and 126, respectively, which are arranged to move in the path of the collar or bracket 127, secured at or near the lower end of the pendent rod 128, the said rod being secured to a bar 129, which may be pivoted, as at 130, to a suitable support and which is adapted to be engaged by the cam projections 131 and 132, projecting outwardly from the disk 133, arranged on the transverse shaft 116, in order that when the slide 106, together with the rocking arm or block 122, is advanced so that the stud 125 is in the path of the vertical movement of the bracket 127 the cam projection 131, acting upon the rod 129, will raise the bracket and tilt the arm to the position shown in the drawings. At the proper time by further advancing the slide 106 the bracket 127, through the cam projection 132 and the arm 129, will engage the stud or projection 126 on the rocking arm 122 and tilt the same to a medium position or away from the arm or bar carrying the jaw 1071), so that the clamping-jaws may be released from the string to permit the string to slip past the jaws when the latter are forced rearward or outward. The string carried by the clamping-jaws 106 and 1071) when moved forward is passed between the two spring-pressed gripping-jaws 136, which latter are carried by an arm 137, pivoted to the inner end of the sliderod 138, the said arm being normally pressed upwardly by means of a spring, as at 138, or

otherwise. On the arm 137 may be arranged a plate 139, having-its'forward edge beveled and-adapted to engage the inner surface of a bar 140, the said bar extending transversely of the machine and being adapted to operate f the arm 137 of each knotter in unison. bar 140 may be connected to a rod 141, which slides in the bracket or support 53 and has its outer end engaged byan armor lever 142, which is pivoted so as to oseillate on the transverse shaft 143 and has a projecting end provided with a set-screw or other engaging portion adapted to be engaged by the cam 144, which is arranged upon the transverse shaft 145 and is adapted to tilt the arm or lever 142 on its pivot and advance the bar 140 and,

through the plate 139, force the rod 138 andv arm 137 forward and downward into the position shown in dotted lines in Fig. 8, the said bar 140 being returned to its normal position by means of a spring 146, having one-endH thereof secured to the bar and its other end secured'to the bracket or support53, the slide-rod 138 being returned by means* of a spring, as at 147.

ranged transversely of the support or bracket 53 and has its upper end fitting over the rod or bar 141 and has its lower end slotted, so as to span the rod 138 of each knotter, the

rod 141 being reduced in size so as to permitand forced to the position shown-in dotted lines, so as to carry the end of the string below the 'path of movement of the carrying and clamping jaws 106 and 1071. The clampingjaws are now advanced by means of the mechanism heretofore described to a point sub- IIO stantially midway over the opening 58 and between the compressing-jaws, so as to double or form the string in the shape of a loop, as shown diagrammatically by broken lines-in Fig. 8, the clamping-jaws being frictionally held in this position by a pin or lug 149a on the pitman engaging a recess in the upper surface of the spring-pressed yielding stop or block 1491. At this time the loop is doubled over upon itself in the form shown in Fig.10. To secure this result, the arm 150 may be pivoted to the bracket 150, projecting outwardly from the support 53, which has its inner end 151 arranged in the path of the loop and its other or outer end pivoted to a link, as at 151, this link being pivoted to a sliding rod 152, arranged in the bracket 53, and has its outer end engaged by the lower end of an arm or lever' 153, pivoted so as to oscillate on the transverse shaft 143 and provided atits upper end with an adjustable bolt or other engag- 1 ing portion, which is adapted to be engaged by a cam 154, secured to the transverse shaft 145, so that the rods or cams will engage the bolt or projection on the lever 153 and carry the sliding rod 152 rearward and, through the link 151, throw the end 151 of the arm 150 inward, so as to double the loop upon itself, a spring 155 being provided to return the arm to its normal position or that shown in Fig. 9.

The upper and lower members of the loop may be doubled or folded over to the position shown in Fig. 11 by means of the inwardlyprojecting forward end of the lever or arm 156. This arm may have a portion thereof arranged in a suitable bracket, as at 156% which may be pivoted to the slide 106, as at 157, and yieldingly connected to said bracket by means of a spring 158, arranged between the bracket and a suitable collar secured on said arm or lever. The outer end of the arm 156 is arranged in the path of movement of the rocking lever 159, which latteris arranged on the transverse shaft 111 and has a suitable projecting portion thereon adapted to be engaged by a cam 160, secured to the transverse shaft 116, so that as said cam rotates the lever will be rocked on its shaft and force the rod or arm 156 forward, so as to tilt the same or throw the forward edge thereof inwardly and double the loop over to the position shown in Fig. 11. At this time the sliding rods 141 and 138 are permitted to return to their normal position, and in doing so the end of the string or twine carried by the clamping-jaws 136 will be passed through the loop and engaged by the gripping device 161. This device has one member 162 slidably held in the support or frame 53, at or near one end of which is pivoted a second or clamping member 163, as at 164, said members having clamping ends or jaws normally pressed apart by means of a spring 165. The end of the member 162 is engaged by a lever 166, pivoted so as to oscillate on the transverse shaft 143 and provided with a projecting portion 167, adapted to be engaged by a cam 168 for forcing said member rearwardly, and With a projection 169, adapted to be engaged by a cam 170 for restoring said member to its normal position. The member 163 of the gripping device has one end thereof, as at 171, beveled or inclined and adapted to engage a beveled or inclined portion of the support 53, as at 172, so that immediately as the arm or lever 166 is forced so as to throw the member 162 outwardly or rearwardly the action of the beveled portion 172 upon the end 171 will close the member 163, so as to grip the string or twine, and by further movement thereof the bend of the loop will move inwardly across over the end of the cord engaged by the gripping device, so as to cause the two portions to slip and interlock, as in Fig. 2, and on further separation of the gripping-jaws will tie the knot, as shown in Fig. 13.

To cut the string in advance of the jaws after the knot has been tied, we may arrange two slidable rods or bars 173 and 174, which are slidably held in the compressing-jaws 51 and are provided with teeth 175 and 176, re` s'pectively, one set of said teeth, as 17 6, being preferably provided with a recess or opening to hold or support the twine while being cut and both teeth being beveled so as to separate or divide the cord by a shearing action. The outer ends of the rods 173 and 174 are normally pressed in one direction by means of a spring, as 177, and each rod is adapted to be engaged at the proper time by the lower end of the pivoted arm 178, arranged upon the rod 54, the arm having its upper end adapted to be engaged by a suitable cam, as at 179, secured to the main driving-shaft 55 of the knotting mechanism, the said shaft being provided with a pulley, as at 180, which may be driven in any suitable manner. The rod 54 is provided with arms 181 and 181, which engage slidable clutches (not shown) on the shaft 55, and is secured in any desired manner to the standard 182, (shown in dotted lines in Fig. 1,) which is carried by the slidable block 60 of the compression mechanism, so that as the jaws open the rod 54 will disengage the clutches, so as to cause the shaft 55 to operate independently of the knotting mechanism, while when the jaws are closed the standard 182 and rod 54 will cause the members of the clutches to be engaged, and thus operate the knotting mechanism.

The operation of the machine is as follows: The wood which is fed into the tray 13 is carried by the tray to the opening 18, the tray holding sufficient for a bundle, and when the tray reaches this point it returns empty, the wood falling between the arms 19 19a. A label-strip, which has been advanced beneath the wood by the action of the feed-rolls 33, is caught and held in the manner described by the clamps 43. The strings or twines are carried beneath the labels andthe wood by means of the clamping-jaws 106at and 107", so as to be engaged by the clamping jaws or blocks 136 and rigidly held thereby, at which time the jaw 107b is released from the twine by means of the bracket 127 engaging the pin 126 on the rocking arm or block 122, so as to tilt the same to a medium position, the bracket 127 being secured to the rod 128 and raised by the cam 132 on the disk 133 engaging the rod 129. The slide 106 is now retired or forced rearward by means of the cam 116 on the disk 118 engaging the sliding block 119,which, through the pin 121, rocks the arm or lever 111 on the shaft 1119. The jaws 51 then open .by reason of the driving connection already described, thus opening the arms 19 19a, so that thewood falls downward between the jaws, carrying with it the labels referred to and the strings,the latter at this time being held at one end by the clamping-jaws 136 and being fed from the sources of supply through the clamping-jaws 106a and 107". At this point the jaws are closed by the camand-lever mechanism described, thus firmly compressing the wood and allowing the forming-arms 19 19a to close by gravity, ready to IOO IIO

receive a new supply of wood. The rod 141 of the knotting mechanism is now forced inwardly by means of the arm or lever 112, so as to tilt the arm 137 on its pivot and force said arm and the rod 138 inwardly, so that the end of the string will project upwardly, as shown in dotted lines in Fig. 8. The rocking arm 122 is now forced to the position shown in the drawings by means of the bracket 127 engaging the pin or projection 125 on said arm, the bracket in this instance being raised by means of the cam 131 on the disk 133 engaging the pivoted arm 129, and through the action of the block 121 on the rocking arm engaging the bar 107 causes the latter to be rocked on its pivot 107, thus rigidly gripping the string or twine between the jaws 106 and 107i. The slide 106is then advanced or moved inwardly to substantially the central vertical plane of the opening 58, during which movement, owing to the rigidity of the string or twine, a loop substantially of the form of that shown by short and long dotted lines in Fig. 8 will be formed, the position of the clamping-jaws 106 and 107b being at this time about mid way between the jaws 51. The arm 150 is now operated by means of the lever or arm 153, through the link 151 and sliding rod 152, so as to throw the inner end 151 of said arm inwardly and double the loop upon itself, as shown in Fig. 10. The folding-arm 156 is then operated by means of a lever 159, so as to double or fold the members of the loop, as shown in Fig. 11. At this time the rod 138 will return to its normal position, and in so doing the end of the string, which now extends upwardly, will be passed through the folded loop by the upward movement of the arm 137, as shown in dotted lines in Fig. 11, and will be engaged by means of the gripping or holding device 161,whieh at this time is being moved rearward by means ot' the lever 166 and the cam projection 168 on the shaft 145. As the gripping device 161 moves rearwardly or outwardly, carrying with it the end of the twine, the gripping-jaws 106 and 107b will also be retired or forced outwardly by means of the cam 117 engaging the sliding block 119, so as to tilt the lever 111 on the shaft 111 and through the link or pitman 110 force the slide 106 .in the same direction, thus rigidly securing the parts and forming the knot, as shown in Fig. 13. The twine or string may now be separated. by means of the teeth 175 and 176 on the slidable rods 173 and 174, respectively, as already described, andthe parts operated so as to bring the string in position beneath the next bundle in the forming-arms 19 19, The compressing-jaws 51 now open and the long bundle falls downward upon the carrier 86, which moves forward, being stepped along bythe ratchet-and-lever mechanism already described, and the bundle is then cut up into suitable lengths.

From the foregoing description it will be seen that everything is automatic, that the wood is firmly compressed, and that as the bundle is very long the wood is rapidly bundled, because each long bundle when severed makes several of commercial length.
